Corbin Burnes and the Ways We Try To Make Sense of All of This
At the beginning of last season, my colleague Ben Clemens examined Milwaukee Brewers right-hander Corbin Burnes in something of a study into what pitchers can control, and which skills can be demonstrated fastest. Burnes had made just one start at the time, striking out 12 batters against one walk in five innings, while also allowing six hits including three homers. More illustrative than those results, however, were Burnes’ elite spin rates. Spin doesn’t take several outings to stabilize, and it isn’t something a pitcher flukes in and out of. Like velocity or foot speed, it is something one either possesses or doesn’t. Burnes has it. Ben’s a smart guy, so he hypothesized that it was likely those spin rates would help keep Burnes’ strikeout numbers high in future appearances, while his home run rates should taper off. Because really, who has that kind of stuff and still gives up three homers a game?
Well, in Burnes’ next start after that piece ran, he gave up three home runs again. In the start after that, he gave up another three. And in the start after that, he gave up two more. Then he moved to the bullpen, where he was fine for a couple of weeks — until Atlanta hammered three dingers off of him in just two-thirds of an inning. Burnes finished the season with 12.86 strikeouts per nine, and 3.12 homers allowed per nine. When opponents hit fly balls against him, 38.6% left the yard — the highest single-season HR/FB rate on record for anyone with at least 40 innings pitched. When he kept the ball in play, he was also historically unlucky; his opponents’ .414 BABIP was the fourth-highest on record. Burnes can say more about himself with a single pitch than just about anyone else, and yet his entire 2019 season only served as an example of all that can happen that’s outside a pitcher’s control.
Somehow, Burnes is having that kind of season again in 2020 — just in the opposite direction. Last year, he allowed 70 hits and 17 home runs in 49 innings. This year, he’s thrown 45.1 innings, and has allowed 22 hits and one home run. His 2.9% HR/FB rate is the second-lowest of any qualified starter, and his .233 BABIP is seventh-lowest. In a single year, he has transformed from, statistically speaking, possibly the unluckiest pitcher we’ve ever seen into the one of the luckiest of this season. What does that mean for Burnes, and for the way we talk about luck in baseball? Read the rest of this entry »
